WEB FEEDING AND CUTTING DEV ICE.

Specification of Letters Patent.

Patented Aug. 22, 1916.

Application filed August '7, 1914. Serial No. 855,645.

T 0 all whom it may concern:

Be it known that I, CHARLES A. J UENGST, a citizen of the United States,and a resident of Croton Falls, in thecounty of Westchester and State ofNew York, have in" vented certain new and useful Improvements in )VebFeeding and Cutting Devices, of which the following is a specification.

In book covering machines for covering books that have not beenpreviously stitched, it is customary to interpose a strip of reinforcingmaterial between the back of the book and the cover.

The main object of the present invention is to feed such reinforcingmeans inthe form of a web and to sever the same into strips as it isused. 7

The invention consists of the features of construction, combination ofparts and arrangement of elements as set forth in the claims heretoappended, a preferred form of which is disclosed in the presentspecification and accompanying drawings. W

In the said drawings: Figure 1 is a side elevation of the crash feeddevice and cover drum. Fig. 2 is a plan view of the crash feed deviceshown in Fig. 1. Fig. 3 is a detail sectional view on the line 3-3 of-Fig. 1. Fig. tis an end view of the parts shown in Fig. 1, looking inthe direction of the arrow 1.

Similar characters of reference indicate corresponding parts in thedifierent views.

1 is the book advanced by a suitable book conveyor (not shown) with itsback lowermost. The back of the book is supplied with an adhesive in awell known manner before it reaches the endless cover presser or drum113. The cover 114: is fed to this drum by any suitable means not shown.The web 116 of reinforcing material (crash or cheesecloth) is fed from asuitable reel (not shown).

117 and 118 indicate two feed rolls mounted adjacent to the path of thebook conveyer. Between these two rolls the web 116 is led by means ofthe idler 119 and guides 120. The roll 117 is mounted on the relativelystationary bearing 120 while the roll 118 is mounted on the arm 121connected to the rocking member 122, here shown as a sleeve, on theshaft 123. Connected to the arm 121 is a lever 124 which extendsdownwardly and is actuated from a suitable cam (not shown). Carried byeach of the rolls 117 and 118 is a sprocket wheel 128. A

way the proper rotation is given to the rolls 117 and 118, theseparation of the said rolls being also permitted by this construction.

Mounted underneath the path of the web 116 and transversely thereof is astationary cutting member 131 Located above the path of the web 116a'ndextending transversely thereof is movable cutting member 132. Thismember 132 is mounted on the rocking support 133 and is normally heldout of engagement with the web bymeans of the spring 134. Connected tothe rocking sleeve 122 is an extension 135 having a bifurcated end 136which engages the end of the cutting member 132.

It will now be apparent that the rotation of the rolls 117 and 118 willfeed the web forward in between the book and the cover presser and thatthe latter will apply both simultaneously to the book as the latterpasses over the cover presser. At the proper time in the cycle ofoperations the cam (not shown) will actuate the sleeve 122 whereby thecutting member 132 will sever the web, and at the same time the rolls117 and 118 will become separated, thereby interrupting the feed of theweb.

What is claimed, is:

1. In a machine of the character set forth, a pair of friction rollsadapted to' feed a web of material between them, a cutting device in thepath of the web, and a unitary member connected to said cutting deviceand to one of said rolls and operable to simultaneously actuate thecutting device and separate the rolls.

2. In a machine of the character set'forth, means for feeding a web ofmaterial, means for severing the web of materiahand a unitary memberconnected to said severing means and to said feeding means and operableto simultaneously actuate said severing means and interrupt theoperation of said feeding means.

3. In a machine of the character set forth, a pair of friction rollsadapted to feed a web of material between them, a cutting member in thepath of the web, and a-movable member supporting one of said rolls tomove it toward and away from the other roll, said movable member beingin operative engagement with said cutting member.

4. In a machine of the character set forth, means for feeding a Web ofmaterial, a rock ing cutting member located adjacent to the path of theWeb, a spring device for normally holding said cutting member out of thepath of the Web and said feeding means in operative condition, and meansfor rocking said cut-ting member, in opposition to the spring device, tosever the Web and to interrupt the operation of the feeding means in asingle movement in one direction.

5. In a machine of the character set forth, rolls for feeding a Web ofmaterial, a cutting member located adjacent to the path of the Web, aspring device for normally holding said cutting member out of the pathof the Web, a movable member carrying one of said rolls and engagingsaid cutting member to operate said cutting member in oppositionto saidspring device and to separate the rolls.

Signed at New York city, in the of New York and State of New York, this6th day of August, A. D. 1914:.
